SAMUEL L. NEELY, OF PIERRON, ILLINOIS.

NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 630,919, dated August 15, 1899.

Application filed May 26,1899, Serial No. 718,465. (No model.)

To aZZ whom it may concern:

Be it known that I, SAMUEL L. NEELY, a citizen of the United States, residing at Pierron, in the county of Bond and State of Illinois, have invented a new and useful Nut- Lock, of which the following is a specification.

My invention relates to nut-locks,and has for its object to provide a simple and efficient nut-lock adapted for preventing the loosening or accidental removal of a nut by jarring or otherwise, and particularly to provide a nut-lock adapted for use in connection with a track-circuit-closing device shown and described in a pending application filed by me of even date herewith.

The object of the invention is to provide a nut-lock of such a construction as to adapt the nut to be released for removal when required, and hence to provide a nut-locking device which is operative without causing mutilation of the nut.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims, it being understood that the improvement is susceptible of various changes in the form, proportion, and minor details of construction Without departing from the spirit or sacrificing any of the advantages thereof.

In the drawings, Figure 1 is a perspective view of a nut-lock constructed in accordance with my invention applied in the operative position to anut. Fig. 2 is a vertical central sectional view of the same. Fig. 3 is a detail view of the nut-clamp detached.

Similar reference characters indicate corresponding parts in all the figures of the drawings.

In the preferred embodiment of myinvention I employ a clamp adapted for engaging a nut, the same consisting of a face-plate 1, having upstruck end portions or ears 2 for contact with opposite side surfaces of the nut, said face-plate being adapted to bear against the exposed surface of the nut, and in said face-plate is formed an opening 3 for the reception of the bolt at, upon which the nut 5 is threaded. Attached to the clamp or formed integral therewith is an eye 6, which in the construction illustrated is formed as a proj ecting portion of an attached strip 7, riveted to one of the ears of the clamp. In the opening of this eye is fitted a split key 8, which also engages a transverse opening 9 in the bolt. It is obvious that after threading the nut upon the bolt and securing it to the desired adjustment the clamp may be fitted thereon and the key inserted through the eye and a registering opening in the bolt to lock the nut against displacement. It is not necessary for the efficiency of the lock that the face-plate of the clamp should bear against the front or exposed surface of the nut, as the upstruck terminal portions or cars of the faceplate are adapted to engage the nut in a variety of positions, and also under conditions where various adjustments of the nut are possible a plurality of transverse openings may be formed in the bolt to provide for relative adjustments of the clamp. The opening which is provided for the reception of the key may be comparatively small and detract but slightly from the strength of the bolt, and inasmuch as there is a considerable latitude of adjustment of the nut for one position of the clamp it will be seen that the clamp embodying my invention may be applied with economy under varying conditions.

Having described my invention, what I claim isl. A nutlock, having a ciamp provided with a face-plate having a central opening, and upstruck ears for engaging opposite sides of a nut, an eye projecting from the face-plate of the clamp in a direction opposite that of the ears, and a split key fitted in said eye and adapted for engagement with a transverse opening in a bolt.

2. A nut -1ock having a clamp provided with a face-plate having a central opening, and upstruck ears for engaging opposite sides of a nut, and an eye projecting from the face plate of the clamp, and a split key fitted in said eye and adapted for engagement with a transverse opening in a bolt, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

SAMUEL L. NEELY.
